            我是以容器outerHTML作为模板,count的值是
            <span>{{count}}</span>
        </h1>
    </div>

    <script>
      Vue.config.productionTip = false;

      const vm = new Vue({
        // el: "#app",
        data(){
            return{
                count:0,
            };
        },
      });

      //$mount挂载和了配置挂载是一样的,但是可以进行设置定时器进行延迟挂载
      setTimeout(() => {
        vm.$mount("#app");
      }, 3000);
    </script>
  </body>
